The latency increase and bandwidth drop occur at 451. At 450 everything is fine. Its not the ram freq, its the bus.

can any 1 write down overclocking volt nb sb vcore speed mhz fsb i can get 3650mhz 1111mhz memory 5.5.5.15
i wanna get 4ghz and max memory speed
Ensure you are updated to 1301 bios.
For 3650 (1600 freq), I used 1.2750 as bios Vore, or with 1301, leave it on auto.
Leave other voltages other than you specific ram voltage, at auto.
At the bottom there are 5 reference voltages
+20
+20
+20
REF
REF
You should be able to easily run at 4050 (1.4125v bios, others at auto) with your rig, as it is very similar to mine. I do 4050 (1800 freq) as my everyday speed. reference voltages remain the same.

not really sure how to explain that... if I put my FSB to 450 I can only put my ram at 900 with 4.4.4.10 CR 1 anything over that isn't worth the performance drop
Just finished doing that "lapping" on my CPU and CPU cooler, and Damm! it works fine! its knocked 8c off my idle temperature and 10c on my load temperature, never thought it would work so well, was also a little risk but was well worth it. atm im at 33-36 idle on all cores and 58-61 on load <3
To better explain what I meant, here are two tests, with most settings as identical as possible. All I did was increase the FSB by 1 (450 to 451), by increasing the cpu freq from 1800 to 1804. I had to increase the ram freq by 0.5 just to get a close setting divider.
You can also see that increasing ram freq (1080 to 1200 in this case) increases bandwidth and reduces latency, so the only number we are truly concerned with is the FSB
You have it made, holystarlight, with that processor. All you have to do is increase the multiplier, keeping the FSB at 450 or under.

I'll drop the multi to 8.5 (1868*8.5) and test at 467. That will bring the mhz (3967) to almost the same as 1800*9 (4050mhz)

That works for me. Good call!
I'm going to try higher clocks now and see if it continues to work at 4.5 Ghz
4.5 Ghz, 500 FSB synced. Very nice, best bandwidth yet!
Nice! I cant get mine to load windows at 500fsb no matter what multi. It will POST, but bluescreens . Would you mind giving me your bios settings? Also are you stable at 4500? What batch is your CPU? Thanks!!
Damn it... Wish I had my board to test these theories with the Q6600
If you get a bsod, increase the Vcore voltage. I do it in increments of 0.250. You might find that you can get further into windows each time you increase it. Once in, you can increase it or decrease it as required to maintain stability.
If you are on 1301, then you can run the rest of the volt settings on auto (with the exception of the ram volts), but reference voltages below I set manually:
1800 FSB
+20
+20
DDR Controller +20
Ram 1 REF
Ram 2 REF
2000 FSB
+30
+30
DDR Controller +20
Ram 1 REF
Ram 2 REF
4500... not stable, 3DMarks for me and runs Orthos, but will not run SuperPi wthout an error. I'm going to lap the cpu tomorrow to perhaps help stability.
Holy $#1T holystarlight - you don't hang around do you!Quote:

Good to hear it did the trick anyway!
If you're lucky you might see a further drop as your thermal paste cures.
Yeh I think i messed things up the first time round added too much thermal paste but I was to lazy to open up the system but with a good reason like lapping just had to! :p:Quote:

any news on any other BIOS btw? have to say 1301 hasn't been that stable with me
sadly the 467 FSB isn't working for me

i cant set my memory to 4-4-4-12
Yeh same, but what you have there is fine anyway. dont look like you have anything ram problems :p:Quote:

That seems to be the best mine can do also.
I think I have 3.6GHz stable...
Best bench for me so far...
Lapped CPU.
UpdatedXP Pro 32 to SP3
Uninstalled beta 7516 driver and reinstalled eVGA 7516 drivers.
Tweaked and tweaked.
New 3DMark high score of 20,351 http://service.futuremark.com/compare?3dm06=6706009
Nice going Hor$eman :)
I'm trying to improve my bandwidth/memory speed, but not having much luck so far. 1800:540, 1800:533, and 1800:600 were non starters, but I was able to boot with 1804:533. Unfortunately, the bandwidth and latency were both worse than before (1800:400).
Is there anything else I can try that might work?
Same, I have tried so many different combo's but no luck, only one that works for me is 1440:540 5.4.4.10, :p:Quote:

You cannot compare duals and quads, mostly there's also a difference between 45 and 65nm CPU's... it's all bios/cpu/ramtype/ram amount/divider related like in the good ol' 680i days...
do ya think a bios update could fix the problem if there was a bios update to fix this issue?Quote:
